To all whomlz'tmay concerm;

Be it known that I, VVALno DUANE Tnow, a citizen of the United States, residing at Kalispell, in the county of Flathead and State of l\Iontana,have inventedi-new and useful Improvements in Railway-lies, of

which the following is a specificatioii.

This invention relates to improvements in the construction of ties for railway rails.

An object of the invention is to produce a reinforced concrete tie constructed insuch a manner as to withstand the shock and jar incident to the-weight of the rolling stock the ordinary wooden tie.

passing thereover and to afford a, resilieney for the rails that will at least equal that of Another object of the invention is to con; struct a reinforced concrete tiewith trough members to receive wooden or other resilient cushion blocks'upon which the rails rest, and to secure the said cushion blocks in the said troughs against accidental removal or displacement, but at thesame time topermit of the removal of the. said blocks when the same become-worn and are to be replaced; A furtherobject of the invention is to construct a flexible reinforced plastic tie having simpleand practical means associated therewith whereby the rails "may be eilectively secured thereon.

A still further object of the invention is to construct a reinforced plastic tie in such a manner that the rails will be cushioned thereon and insulated from the tie, so that the operation of the signals will not be interfered with or the current flowing through the rails short circuited. a

' It isa still further object of the invention to provide a reinforced plastic tie which shall be of a simple but strong and effective const-ruction and which shall impart the desired amount of yieldability to the rails, andwherein the third rail of a three-rail system -may be effectively connected with the ties.

With the above and other objects iii view,

1 the improvement resides in the construction,

combination and arrangement of parts set forth in the following specification and" falling within the scope of the appended claims.

approximately..on the line 3 3 of Fig-2,

,Fig. 4 is a horizontal sectional view approximatch' on the line of Fig. 3, Fig. 5 is a perspective view of a rail clamp which is adapted to be emplo ;ed in connection with my tie, Fig. (i is a central longitudinal sectional view through a modified form of the i tie, Fig. 7 is a longitudinal sectional view through a still. further modified form of the tie, Figs. 8 to ll illustratedifferent manners in which therailmay be clamped upon the tie. and Figs. 12 to 16 are end viewsf The tie is i'ormed'on or oil the roadbed in a suitable mold, and before the concrete body is arranged therein I provide a central metallic strip which may have its ends oil'- set in a vertical direction, as indicated by the numerals 2, and is straight jl'or a suitable distance from the said oil'sct ends, as indicated by the n1uneral3,while an arched central portion 4 connects the said straight portions Around the arched portion- 4. and

The concrete (3, in the preferred form of my improven'ient is tamped to embrace the major port ion of the arch 4; and the straight portions 3 and the angular ends 2 of the rethe vertical end 2 I arrange a Wire mesh 5,

ini'orcing member 1, leaving a space 7 at the center of the tie, and preferably the bottom of the tie adjacent to. the said center is cutawayin a curved line, as ihdicated by the numerals 8. By this arrangement it will be note ltliat the arched metal member 4: andthe wire netting can: centrally exposed and that the end portionsof the tie are'permitted to bend upon the said central portions of tlfe metal n'iembers, so that when the tie is placed in the roadbcd one of the ends thereof may move vertically independent of the other, and as a consequence a yieldable tie is produced' However, and'as illustrated straight walls of transversely arrangidi.

troughs 11. A sheet of fiber or other insulating material 12 is arranged between metalv rein'hircements f).

the troughs and the straight portions 3 of the reinioreing member 1, and also flanged insulating collars lb may surround v the rivets and lie against the head portions 15 in the ends of the cushion lIlUCh'S 1 7. The

blocks 17 may be also secured in the troughs by spikes or nails 18 which are driven angularlv threiugh the side trough opposite the member H, as illustrated in Fig. 3 of the dra w i n 1 a The sides of the troughs are preferably bent outwardly over but in a line with the upper fare of the. tie. and these bent portions are provided with longitiulinally extendhn. key hole slots 19 and the said bent portions or flanges indicated for distinction by the numeral 20 to one oi. the sides of the slot are formed with spa'eed apertures 21.

The numerals 22 indicate the rail engaging elanms which are shaped to lie upon the flanges of the rails :23 and which have their under-faces formed with Thead depending portions El that are adapted to he passed through the enlarged opening 21 of the key hole slot 19 to he slid longitudinally in the reduced portion of the said opening and when in proper position retaining elements, such as pins or hers -25 arr inserted through certain oi the apertures '21.

The baseot the rails may he surronmled by a sheet of insulating material 26. and this material may extend over the flange of the rails so that the rail engaging menihers or clamps 32 will lie upon the said sheet, and whereby the rail is effectively in sulated from the tie.

By reference to the drawings it will he noted that the keyhole slots 1!)" are arranged. at an inclination. and by this arwmgement it will be noted that the rail clamps will he moved inwardly toward the webs of the rails, when the heads thereof are passed through the enlarged openings 21 of the slots and the said members moved in the direetion of the opposite end of the slot. The inner or, engaging end of the member 22 is preferably formed with a downturned lipQQ, and as the head 24 of the member 22 will have a tendency to hold the said member in a'horizontal position,

the lip traveling upon the insulated mu- 'terial 26, arranged upon the said upper faces of the base flanges of the rails, will neeessarily lrietionally engage with the said material, turning the same tightly against the rails. as will, is thought he readily understood.

lhe nun'ierals 2U designate bolt members whieh are arranged on one of the angular ends 2 of the reinforcing menil a'r 1 and which project through one of the ends of the ties. These bolt members as well as the end of the tie have arranged thereon a sheet of insulating material 27. and the bolts are adapted to pass through openings in the vertical arm :8 of a la'aeket member Ell and the said arm is set-lured to the halls lrv nuts 30. The head of the lu'arket comprises a rhannel member to receive the flange ol a third rail 31 and the said flange may be secured to the bracket in any den sired or preferred manner.

In Figs. 8 to ll, I hav illustrated modified forms of means whereby the rail may he clamped upon the tie. and in Figs. 1-2 to 16 I have also illustrated various shapes in which the tie ran he ronslruet'ml,

In Fig. T the reinforcing member 1]. comprises two elements 35 and 36 resiuetively, the same having the arched members lapping: and insulated from eaeh other by a sheet oi suilahle material 36'. The arched members may he left nninsulated however. The overlapping ends are provided each .with a plurality of spaced openings. which when rertain of the same are. brought into register are adapted to rereive securing bolts 37 provided with lt'ilI'ltlllfI nuts 38 By this arralurement it will he noted that while the strength of the reinforcing: member is not materially affected, the ends of the ties may be adjusted toward or away from eael1 0ther.

From the above description taken in con" nertion with the iu-ronnmnving' drawings, the simplieity of'the device as well the advantages thereof will. it is thought, he perl eetlv apparent to those skilled in the art to \vhieh :llur'h invention appertains without further detailed desr'ription.

Having thus described the invention, what I claim is:

1. A tie comprising two plastic: spared members having metal reinforcements eonnet-ting: thesaine, a trough member arranged transversely of each of the plastic ends oi" the tie and supported upon but insulated from the metal reinforcement,'a,

52. A tie for railway rails including a pair of spaced plastic members having metal re inforcements therein and extending through the inner ends of the same, means for ad" justahly eonnertin r the extending ends of said reintoreements, troughs arranged in the plastic ends and commuted to and insulated from the melalreinl'or'relnents said tI'UllfIllB having their upper ends heat over the plastic members at the tie and their saidends pro-- vided with longitudinally extending key hole slots, and apertures disposed adjacent the slots, and said slots adapted to receive T- shaped depending members of rail-engaging elements, and pins passing through the apertures to retain the said elements upon the said ends of the trough.

3. A t-i' comprising spaced plastic members having their lower adjacent edges cutaway, a metal reinforcement in each of the plastic members and projecting through the inner ends thereof, each of said reinforcements having a flat portion having one of its ends straight and bent upwardly in the tie adjacent the end of the tie and its opposite end straight and arched outwardly from the said flat portion and the ends of the arched and straight members adapted to overlap, gneans for adjustably connecting the said ends, a wire mesh wound around tl'ie arched and straight portions of the reinforcements, invertedh lJ -fshaped metal reinforcements arranged below' and secured to the straight portions .of the firsFmntioned reinforcements, a substantially U--sl1aped trough arranged transversely in the plastic ends and secured to the straight portion of each of said reinforcements, a cushion block within each of the troughs to receive a rail, means between the sides of the trough and the cushion blocks for retai'ning the same in the troughs, edges of the troughs for securing the rail upon the cushion block, means for insulating said securing members from the rails, bolt members connected with the angular end of means connected with the upper one of the first mentioned reinforcing members and extending through the ends of one of the plastic members of the tie, and a rail supporting bracket connected to the said boltsr In testimony whereofI afiix my signature in presence of twowitnesses.
